Technical Field

[0001] The embodiments of the present application relate to but are not limited to the field of communication technology, and in particular, to a method for determining transmission power, an electronic device, a terminal device, and a storage medium. Background Art

[0002] Satellite communication is an important part of mobile communications. Satellite communication networks have the characteristics of long communication distance, large coverage area, and flexible networking. In some important fields, such as space communication, aviation communication, military communication, etc., satellite communication technology plays an irreplaceable role. Satellite networks can provide services for both fixed terminals and various mobile terminals.

[0003] In the related art, in order to communicate reliably with a satellite, a terminal device will send information to the satellite at the maximum transmission power of the terminal device. However, this will result in high power consumption of the terminal device. Summary of the invention

[0004] Embodiments of the present application provide a method for determining transmission power, an electronic device, a terminal device, and a storage medium.

[0005] In a first aspect, an embodiment of the present application provides a method for determining transmit power, the method comprising:

[0006] Sending first information and second information to a network device; the first information includes a link request, and the second information includes a first channel quality; the first channel quality is a channel quality between the terminal device and the network device determined by the terminal device;

[0007] receiving third information and fourth information sent by the network device; the third information includes confirmation information of the link request, and the fourth information includes adjustment information of the first channel quality;

[0008] According to the adjustment information of the first channel quality, a target transmission power of the terminal device when communicating with the network device is determined.

[0009] In a second aspect, an embodiment of the present application provides an electronic device, the electronic device comprising:

[0010] A communication unit, configured to send first information and second information to a network device; the first information includes a link request, and the second information includes a first channel quality; the first channel quality is a channel quality between the terminal device and the network device determined by the terminal device;

[0011] The communication unit is further configured to receive third information and fourth information sent by the network device; the third information includes confirmation information of the link request, and the fourth information includes adjustment information of the first channel quality;

[0012] A determination unit is used to determine the target transmission power of the terminal device when communicating with the network device according to the adjustment information of the first channel quality.

[0013] In a third aspect, an embodiment of the present application provides a terminal device, including: a transceiver, a memory, and a processor.

[0014] The transceiver is used for the terminal device to communicate;

[0015] The memory is used to store computer programs.

[0016] The processor is used to call and run the computer program stored in the memory, and in combination with the transceiver, enables the terminal device to execute the method described in the first aspect.

[0017] In a fourth aspect, an embodiment of the present application provides a computer storage medium, wherein the computer storage medium stores one or more programs, and the one or more programs can be executed by one or more processors to implement the method described in the first aspect.

[0018] In an embodiment of the present application, first information and second information are sent to a network device; the first information includes a link request, and the second information includes a first channel quality; the first channel quality is a channel quality between the terminal device and the network device determined by the terminal device; third information and fourth information sent by the network device are received; the third information includes confirmation information of the link request, and the fourth information includes adjustment information of the first channel quality; based on the adjustment information of the first channel quality, a target transmission power of the terminal device when communicating with the network device is determined. In this way, since the target transmission power of the terminal device when communicating with the network device is determined according to the adjustment information of the first channel quality, the target transmission power can be determined according to the channel quality between the terminal device and the network device, thereby not only enabling the terminal device to communicate reliably with the network device, but also enabling the terminal device to no longer use the maximum transmission power to communicate with the network device. The transmission power used by the terminal device is small, which is beneficial to reducing the power consumption of the terminal device. In addition, since the first information and the second information are sent in combination, and the third information and the fourth information are sent in combination, the terminal device receives the third information and the fourth information sent by the network device only after sending the first information and the second information to the network device, thereby enabling the terminal device to send the first information and the second information to the network device at one time, and the network device can also send the third information and the fourth information to the terminal device at one time, avoiding the situation in which the terminal device sends the first information, receives the third information sent by the network device, and then sends the second information and receives the fourth information sent by the network device, thereby wasting signaling resources and extending the information transmission time. Therefore, the present application can save signaling resources and reduce the transmission delay of information. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Communication system scenarios include terrestrial communication networks (TN) and non-terrestrial communication networks (NTN). NTN can provide communication services to ground users by means of satellite communication. NTN systems can include NR-NTN and IoT-NTN systems.

[0047] Figure 1 A schematic diagram of an application scenario of an embodiment of the present application is shown in FIG. Figure 1 As shown, the communication system 100 may be a terrestrial communication network system, and the communication system 100 may include a terminal device 110 and a network device 120. The network device 120 may communicate with the terminal device 110 via an air interface. The terminal device 110 and the network device 120 support multi-service transmission.

[0048] It should be understood that the embodiments of the present application are only exemplified by the communication system 100, but the embodiments of the present application are not limited thereto. That is to say, the technical solution of the embodiment of the present application can be applied to various communication systems, such as: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, Advanced long term evolution (LTE-A) system, New Radio (NR) system, NR system evolution system, LTE on unlicensed spectrum (LTE-based access to unlicensed spectrum, LTE-U) system, NR on unlicensed spectrum (NR-based access to unlicensed spectrum, NR-U) system, Universal Mobile Telecommunication System (UMTS), Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), LTE Time Division Duplex (TDD), ... Wireless Fidelity (WiFi), Wireless Fidelity (WiFi), Wireless Fidelity (WiFi), Wireless Fidelity (WiFi), Wireless Fidelity (WiFi), Wireless Fidelity (WiFi), Wireless Fidelity (WiFi), Wireless Fidelity (LTE), Wireless Fidelity (LTE), Advanced long term evolution (LTE-A), New Radio (NR) system, NR system evolution system, LTE on unlicensed spectrum (LTE-U) system, NR on unlicensed spectrum (NR-based access to unlicensed spectrum, NR-U) system, Universal Mobile Telecommunication System (UMTS), Wireless Local Area Networks (WLAN), Wireless System, UMTS), Internet of Things (IoT) system, Narrow Band Internet of Things (NB-IoT) system, enhanced Machine-Type Communications (eMTC) system, or future communication systems (such as 6G, 7G communication systems), etc.

[0049] The network device 120 may provide communication coverage for a specific geographical area, and may communicate with a terminal device 110 (eg, UE) located within the coverage area.

[0050] Optionally, the terminal device 110 may be any terminal device, including but not limited to a terminal device connected to the network device 120 or other terminal devices by wire or wirelessly.

[0051] Optionally, the terminal device 110 may be used for device-to-device (D2D) communication.

[0052] The network device 120 may include one of the following or a combination of at least two: an evolved base station (eNB or eNodeB) in a Long Term Evolution (LTE) system, a Next Generation Radio Access Network (NG RAN) device, a base station (gNB) in an NR system, a small station, a micro station, a wireless controller in a Cloud Radio Access Network (CRAN), an access point for Wireless-Fidelity (Wi-Fi), a transmission reception point (TRP), a relay station, an access point, a vehicle-mounted device, a wearable device, a hub, a switch, a bridge, a router, a network device in a future evolved Public Land Mobile Network (PLMN), etc.

[0053] Figure 1 One base station and two terminal devices are shown exemplarily. Optionally, the wireless communication system 100 may include multiple base station devices and each base station may include another number of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0054] Non-terrestrial networks (NTN) generally use satellite communications to provide communication services to ground users. Compared with ground cellular network communications, satellite communications have many unique advantages. First, satellite communications are not restricted by user regions. For example, general land communications cannot cover areas such as oceans, mountains, deserts, etc. where communication equipment cannot be set up or where there is no communication coverage due to sparse population. For satellite communications, since one satellite can cover a large area of ​​land, and satellites can orbit the earth, in theory every corner of the earth can be covered by satellite communications. Secondly, satellite communications have great social value. Satellite communications can be covered at a low cost in remote mountainous areas, poor and backward countries or regions, so that people in these areas can enjoy advanced voice communications and mobile Internet technologies, which is conducive to narrowing the digital divide with developed areas and promoting the development of these areas. Thirdly, satellite communications have long distances, and the cost of communications does not increase significantly as the communication distance increases; finally, satellite communications are highly stable and are not restricted by natural disasters.

[0055] Satellite communication refers to a method of communication using artificial satellites. The satellite communication system consists of ground stations, satellites and terminal equipment. The ground station sends information to the satellite via radio waves, and the satellite forwards the information to the ground station in the target area, and then transmits the information to the terminal equipment through the ground station.

[0056] Satellite communications have the advantages of global coverage and no geographical restrictions, and can provide wide-area communication services, regardless of geographical location, weather and other factors. It plays an important role in areas far from land, mountains, oceans, and in specific scenarios such as disaster relief and maritime navigation.

[0057] Satellite communications can realize a variety of communication methods such as voice, data and images, including telephone, Internet access, television broadcasting, etc. At present, satellite communications have been widely used in military, aerospace, telecommunications, radio and television, weather forecasting and other fields.

[0058] With the continuous advancement of technology and the reduction of costs, satellite communications are developing rapidly. The new generation of satellite communication systems will be faster, more efficient and more reliable, providing a wider range of communication services for humans. At the same time, with the continuous introduction of the idea of ​​satellite Internet by 6G communications, the support of satellite functions by terminal equipment has gradually attracted widespread attention from various manufacturers.

[0059] NTN technology can be combined with various communication systems. For example, NTN technology can be combined with NR system to form NR-NTN system. For another example, NTN technology can be combined with Internet of Things (IoT) system to form IoT-NTN system. As an example, IoT-NTN system can include NB-IoT-NTN system and eMTC-NTN system.

[0060] Figure 2 A schematic diagram of the architecture of a communication system provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, Figure 2 The communication system 200 may be a non-terrestrial communication network system, and the communication system 200 includes a terminal device 201 and a satellite 202, and the terminal device 201 and the satellite 202 may communicate wirelessly. The network formed between the terminal device 201 and the satellite 202 may also be referred to as an NTN. Figure 2 In the architecture of the communication system 200 shown, the satellite 202 may have the function of a base station, and the terminal device 201 and the satellite 202 may communicate directly. In the system architecture, the satellite 202 may be referred to as a network device. In some embodiments of the present application, the communication system 200 may include multiple network devices 202, and each network device 202 may include other number of terminal devices within its coverage area, which is not limited in the embodiments of the present application.

[0061] Figure 3 A schematic diagram of another communication system architecture provided in an embodiment of the present application, such as Figure 3 As shown, Figure 3 The communication system 300 may be a non-terrestrial communication network system, and the communication system 300 includes a terminal device 301, a satellite 302, and a base station 303. The terminal device 301 and the satellite 302 may communicate wirelessly, and the satellite 302 and the base station 303 may communicate with each other. The network formed by the terminal device 301, the satellite 302, and the base station 303 may also be referred to as an NTN. Figure 3 In the architecture of the communication system 300 shown, the satellite 302 may not have the function of a base station, and the communication between the terminal device 301 and the base station 303 needs to be transferred through the satellite 302. In this system architecture, the base station 303 can be called a network device. In some embodiments of the present application, the communication system may include multiple base stations 303, and each base station 303 may include other number of terminal devices within its coverage area, which is not limited in the embodiments of the present application. The base station 303 may be Figure 1 The network device 120 in.

[0062] It should be understood that the satellite 202 or satellite 302 includes, but is not limited to: Low-Earth Orbit (LEO) satellite, Medium-Earth Orbit (MEO) satellite, Geostationary Earth Orbit (GEO) satellite, High Elliptical Orbit (HEO) satellite, etc. Satellites can use multiple beams to cover the ground. For example, a satellite can form dozens or even hundreds of beams to cover the ground. In other words, a satellite beam can cover a ground area with a diameter of tens to hundreds of kilometers to ensure satellite coverage and improve the system capacity of the entire satellite communication system.

[0063] As an example, the altitude range of LEO satellites can be 500 km to 1500 km, the corresponding orbital period can be about 1.5 hours to 2 hours, the signal propagation delay of single-hop communication between users can generally be less than 20 milliseconds, the maximum satellite visibility time can be 20 minutes, the signal propagation distance of LEO satellites is short and the link loss is small, and the transmission power requirements of user terminal equipment are not high. The orbital altitude of GEO satellites can be 35786 km, the rotation period around the earth can be 24 hours, and the signal propagation delay of single-hop communication between users can generally be 250 milliseconds.

[0064] In order to ensure satellite coverage and improve the system capacity of the entire satellite communication system, satellites use multiple beams to cover the ground. A satellite can form dozens or even hundreds of beams to cover the ground; a satellite beam can cover a ground area with a diameter of tens to hundreds of kilometers.

[0065] It should be noted that Figures 1 to 3It is only to illustrate the system to which the present application is applicable in the form of an example. Of course, the method shown in the embodiment of the present application can also be applied to other systems. In addition, the terms "system" and "network" are often used interchangeably in this article. The term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship. It should also be understood that the "indication" mentioned in the embodiment of the present application can be a direct indication, an indirect indication, or an indication of an association relationship. For example, A indicates B, which can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, B can be obtained through C; it can also mean that there is an association relationship between A and B. It should also be understood that the "correspondence" mentioned in the embodiment of the present application can mean that there is a direct or indirect correspondence relationship between the two, or it can mean that there is an association relationship between the two, or it can mean that there is an indication and being indicated, configuration and being configured, etc. It should also be understood that the "predefined", "protocol agreed", "predetermined" or "predefined rules" mentioned in the embodiments of the present application can be implemented by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in devices (for example, including terminal devices and network devices), and the present application does not limit its specific implementation method. For example, predefined may refer to the definition in the protocol. It should also be understood that in the embodiments of the present application, the "protocol" may refer to a standard protocol in the field of communications, such as LTE protocols, NR protocols, and related protocols used in future communication systems, and the present application does not limit this.

[0066] Satellites can be divided into two types based on the functions they provide: transparent payload and regenerative payload. For transparent payload satellites, they can provide wireless frequency filtering, frequency conversion and amplification functions, and can provide transparent forwarding of signals without changing the waveform signal they forward. For regenerative payload satellites, in addition to providing wireless frequency filtering, frequency conversion and amplification functions, they can also provide demodulation / decoding, routing / conversion, encoding / modulation functions, and have some or all of the functions of a base station.

[0067] In the NTN, one or more gateways may be included for communication between satellites and terminal devices.

[0068] Figure 4 A schematic diagram of an NTN scenario based on a transparent forwarding satellite provided in an embodiment of the present application, Figure 5A schematic diagram of an NTN scenario based on a regenerative forwarding satellite provided in an embodiment of the present application.

[0069] like Figure 4 As shown in the figure, for the NTN scenario based on transparent forwarding satellite, the gateway and the satellite communicate through the feeder link, and the satellite and the terminal device can communicate through the service link. Figure 5 As shown, for the NTN scenario based on regenerative forwarding satellites, satellites communicate with each other through interstar links, gateways and satellites communicate with each other through feeder links, and satellites and terminal devices communicate with each other through service links.

[0070] Figure 6 A schematic diagram of the positions of LEO, MEO and HEO provided in an embodiment of the present application is shown in FIG. Figure 6 As shown, GEO can also be called a geostationary orbit satellite. Its altitude is fixed at 35,800 km above the earth's equator. A single satellite covers a wide area, and most regional mobile communication services use this orbit; LEO's orbit is between 500-2000 km above the earth's altitude. A single satellite covers a narrow area, and generally multiple satellites are required to form a constellation; MEO is an orbit between LEO and GEO, and it can neutralize the advantages and disadvantages of both low orbit and high orbit.

[0071] Figure 7 A schematic diagram of a communication framework of a terminal device provided in an embodiment of the present application, such as Figure 7As shown, the RF unit of the terminal device can be connected to the low frequency antenna (LB ANT0 and LB ANT1) through relevant circuits, so that the terminal device can receive and transmit low frequency signals. The RF unit of the terminal device can be connected to the medium and high frequency antenna (MHB ANT2 to MHBANT5) through relevant circuits, so that the terminal device can receive and transmit medium and high frequency signals. The RF unit of the terminal device can be connected to the diversity receiver (DRX) antenna (DRX ANT) through a low noise amplifier (LowNoise Amplifier, LNA), and the RF unit of the terminal device can be connected to the primary receiver (PRX) antenna (PRX ANT) through an LNA and a power amplifier (Power Amplifier, PA). In addition, the satellite communication transceiver of the terminal device can also be connected to the DRX ANT through an LNA, and the satellite communication transceiver of the terminal device can also be connected to the PRX ANT through an LNA and a PA. Among them, the RF unit can be applicable to general satellites, and the satellite communication transceiver can be applicable to proprietary satellites.

[0072] Regardless of the satellite communication method, additional power amplifiers (PA) must be added. High-power PAs provide strong support for the uplink signal of the entire satellite system. Currently, due to the lack of protocol intercommunication between various satellite systems, there are also inconsistencies in PA system solutions, but from a physical point of view, a wide-band PA is sufficient to support the transmission of the satellite system. The demand for low-noise amplifiers (LNA) for receiving signals is also a strong requirement. Currently, due to the lack of interaction between satellite systems and cellular systems, some components cannot be reused or reuse will cause deterioration of the cellular.

[0073] Figure 8 A schematic diagram of a scenario in which a terminal device is blocked by a building when communicating with a satellite provided in an embodiment of the present application, such as Figure 8 As shown in the figure, in the transmission path between the satellite and the terminal device, because the satellite is at a certain height of the earth, the signal will encounter a series of buildings or obstacles on the ground during the transmission process, which will cause signal loss between the terminal device and the satellite. The lost signal will cause transmission damage.

[0074] Fig. 9 A schematic diagram of a scenario in which a signal passes through the atmosphere when a terminal device communicates with a satellite provided in an embodiment of the present application, such as Fig. 9 As shown in the figure, the signal sent by the terminal to the satellite will pass through the troposphere, stratosphere, mesosphere, thermosphere and exosphere in turn. Because each layer has different characteristics, the influence it occupies will also be different.

[0075] The troposphere is the lowest layer of the atmosphere. Its height varies with latitude and season. In terms of latitude, the average low latitude is 17-18 kilometers; the average mid-latitude is 10-12 kilometers; and the high latitude is only 8-9 kilometers. In terms of season, the height of the upper boundary of the troposphere is higher in summer than in winter. The troposphere concentrates 3 / 4 of the entire atmospheric mass and almost all water vapor. The most intense changes in the atmosphere are also in this layer, and the most serious impact on signal transmission is also in this layer.

[0076] The stratosphere is 55 kilometers above the top of the troposphere. The airflow in this layer is quite stable and mainly horizontal, hence the name. Modern civil aircraft can fly in the stratosphere.

[0077] The mesosphere is from the top of the stratosphere to an altitude of 85 kilometers. Its main characteristics are: (1) The temperature drops rapidly with increasing altitude, and the temperature at the top of the mesosphere drops to -83℃~-113℃. Because the ozone content in this layer is very small, it cannot absorb a large amount of solar ultraviolet rays, and most of the short-wave radiation that nitrogen and oxygen can absorb is absorbed by the upper atmosphere, so the temperature decreases with increasing altitude. (2) There is strong convection movement, also known as the high-altitude troposphere or upper troposphere. This is because the upper part of this layer of atmosphere is cold and the lower part is warm, causing the air to produce convection movement. However, due to the thin air in this layer, the convection movement of the air cannot be compared with that of the troposphere.

[0078] The thermosphere extends from the top of the mesosphere to an altitude of 800 kilometers. The density of this layer of atmosphere is very small. In the 700-kilometer-thick air layer, it only contains 0.5% of the total mass of the atmosphere. Characteristics of the thermosphere: (1) The temperature rises rapidly with increasing altitude. According to detection, the temperature can reach over 1000°C at an altitude of 300 kilometers. This is because all solar ultraviolet radiation with a wavelength less than 0.175 microns is absorbed by the atmospheric matter in this layer, causing it to warm up. (2) The air is in a highly ionized state. The air density of this layer is very small. At an altitude of 270 kilometers, the air density is about one billionth of the air density on the ground. Due to the low air density, under the action of solar ultraviolet rays and cosmic rays, oxygen molecules and some nitrogen molecules are decomposed and are in a highly ionized state, so the thermosphere is also called the ionosphere. The ionosphere has the ability to reflect radio waves, which is of great significance to radio communications.

[0079] The area above the thermosphere is called the exosphere. It is the outermost layer of the atmosphere and the transition layer between the atmosphere and interstellar space, but there is no obvious boundary line. In this layer, the air is extremely thin, and there is little chance of collision between atmospheric particles. The temperature also rises with increasing altitude. Due to the high temperature, the air particles move very fast, and because they are far from the earth's surface, they are less affected by the earth's gravity, so some high-speed moving air particles continue to dissipate into interstellar space, hence the name of the exosphere. According to cosmic rocket data, in the space outside the earth's atmosphere, there is also an extremely thin atmosphere composed of ionized gases, called the "geocoron". It stretches to an altitude of 22,000 kilometers. It can be seen that the atmosphere and interstellar space are gradually transitioned and there is no clear boundary.

[0080] In the related art, in satellite communications, the signal transmission quality of the terminal device will be affected by multiple factors such as the atmosphere and / or obstacles. At the same time, because the distance between the satellite and the terminal device is very far, the signal transmission time will be very long. In the related art, the terminal device is required to inform the satellite of the terminal device's location information.

[0081] Fig.10 A schematic diagram of the process of terminal equipment and satellite communication provided for related technologies, such as Fig.10 As shown, first, the terminal device searches for the satellite through the satellite search process, then the terminal device connects to the satellite, and then the terminal device establishes communication with the satellite.

[0082] Fig.11 Another schematic diagram of the process of terminal equipment communicating with satellite provided for related technologies, such as Fig.11 As shown, first, the terminal device searches for a satellite through a satellite search process, for example, the terminal device searches for a satellite according to the maximum power, then the terminal device initiates a link request to the satellite, the satellite sends a response or confirmation information of the link request to the terminal device, then the terminal device sends the location information of the terminal device to the satellite, and the satellite sends the link budget adjustment information (which may be the adjustment information of the first channel quality described below) to the terminal device. The link budget is the calculation of all gains and attenuations in the transmitter, communication link, propagation environment (atmosphere, coaxial cable, waveguide, optical fiber, etc.) and receiver in a communication system.

[0083] In the related art, after the terminal device searches for a satellite through the satellite search process, the terminal device first executes the process of connecting to the satellite, and then executes the process of sending location information to the satellite, which results in a long time spent by the terminal device to send the location to the satellite. In addition, the power used when the terminal device communicates with the satellite is the maximum transmission power of the terminal device, which makes the power consumption of the terminal device high.

[0084] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and they all belong to the protection scope of the embodiments of the present application.

[0094] In some embodiments, the channel quality between the terminal device and the network device determined by the terminal device may be the channel quality between the terminal device and the network device estimated by the terminal device. In some embodiments, the channel quality may be used to indicate the attenuation between the terminal device and the network device.

In some embodiments, the channel quality may include a channel quality indicator (Channel Quality Indicator, CQI).

[0097] In some embodiments, the third information and the fourth information may be included in one signaling. Exemplarily, the network device sends information of multiple second time units to the terminal device, and the information of the multiple second time units includes the third information and the fourth information. In some embodiments, the third information and the fourth information are continuous in time / time domain, or the third information and the fourth information are discontinuous in time / time domain. For example, the third information occupies the first at least one second time unit of the multiple second time units, and the fourth information occupies at least one second time unit of the multiple first time units after the first at least one second time unit; wherein, the first at least one second time unit and the at least one second time unit after the first at least one second time unit may be continuous or separated by one or more second time units.

In some embodiments, the duration corresponding to the first time unit may be the same as the duration corresponding to the second time unit. In other embodiments, the duration corresponding to the first time unit may be different from the duration corresponding to the second time unit. In some embodiments, the number of first time units in a plurality of first time units may be the same as the number of second time units in a plurality of second time units. For example, the number of first time units in a plurality of first time units is 5, and the number of second time units in a plurality of second time units is also 5.

[0100] In some embodiments, the adjustment information of the first channel quality may include adjustment information for adjusting the first channel quality, so that the terminal device can adjust the first channel quality according to the adjustment information of the first channel quality to obtain the second channel quality. In some embodiments, the adjustment information for adjusting the first channel quality may be 0. In other embodiments, the adjustment information of the first channel quality may include the second channel quality obtained after adjusting the first channel quality.

[0101] In some embodiments, the network device may determine the adjustment information of the first channel quality according to the reception quality of the first information and / or the reception quality of the second information. For example, when the reception quality of the first information is less than or equal to the first threshold, and / or the reception quality of the second information is less than or equal to the second threshold, it is determined that the estimation of the first channel quality is too high, and the second channel quality obtained is worse than the first channel quality. For another example, when the reception quality of the first information is greater than the first threshold, and / or the reception quality of the second information is greater than the second threshold, it is determined that the estimation of the first channel quality is too low, and the second channel quality obtained is higher than the first channel quality, or the second channel quality obtained is equal to the first channel quality. In some embodiments, the network device may determine the adjustment information of the first channel quality according to the difference between the reception quality of the first information and the first threshold, and / or the difference between the reception quality of the second information and the second threshold. In some embodiments, the network device may also determine the adjustment information of the first channel quality according to at least one of the distance between the terminal device and the network device, the location environment information of the terminal device, the air parameter information between the terminal device and the network device, and / or the reception quality of the first information and / or the reception quality of the second information. In some other embodiments, the network device may determine the adjustment information of the first channel quality according to the difference between the reception quality of the first information and the reception quality of the second information.

[0102] In some embodiments, determining the target transmission power of the terminal device when communicating with the network device based on the adjustment information of the first channel quality may include: determining the second channel quality based on the adjustment information of the first channel quality, and determining the target transmission power of the terminal device when communicating with the network device based on the second channel quality. In other embodiments, determining the target transmission power of the terminal device when communicating with the network device based on the adjustment information of the first channel quality may include: adjusting the transmission power of the terminal device when sending the first information and / or the second information based on the adjustment information of the first channel quality, to obtain the target transmission power of the terminal device when communicating with the network device.

[0103] In an embodiment of the present application, first information and second information are sent to a network device; the first information includes a link request, and the second information includes a first channel quality; the first channel quality is a channel quality between the terminal device and the network device determined by the terminal device; third information and fourth information sent by the network device are received; the third information includes confirmation information of the link request, and the fourth information includes adjustment information of the first channel quality; based on the adjustment information of the first channel quality, a target transmission power of the terminal device when communicating with the network device is determined. In this way, since the target transmission power of the terminal device when communicating with the network device is determined according to the adjustment information of the first channel quality, the target transmission power can be determined according to the channel quality between the terminal device and the network device, thereby not only enabling the terminal device to communicate reliably with the network device, but also enabling the terminal device to no longer use the maximum transmission power to communicate with the network device. The transmission power used by the terminal device is small, which is beneficial to reducing the power consumption of the terminal device. In addition, since the first information and the second information are sent in combination, and the third information and the fourth information are sent in combination, the terminal device receives the third information and the fourth information sent by the network device only after sending the first information and the second information to the network device, thereby enabling the terminal device to send the first information and the second information to the network device at one time, and the network device can also send the third information and the fourth information to the terminal device at one time, avoiding the situation in which the terminal device sends the first information, receives the third information sent by the network device, and then sends the second information and receives the fourth information sent by the network device, thereby wasting signaling resources and extending the information transmission time. Therefore, the present application can save signaling resources and reduce the transmission delay of information.

[0104] In some embodiments, sending the first information and the second information to the network device includes:

[0105] Sending the first information to the network device at a first transmission power, and sending the second information to the network device at a second transmission power;

[0106] The first transmission power is the maximum transmission power of the terminal device, and the second transmission power is less than or equal to the first transmission power.

[0107] In some embodiments, the first transmission power is different from the second transmission power, so that the network device can determine the adjustment information of the first channel quality according to the difference information between the reception quality of the first information and the reception quality of the second information. Taking the reception quality of information including bit error rate and / or packet loss rate as an example, for example, when the second transmission power is less than the first transmission power, but the network device obtains the bit error rate and / or packet loss rate of the second information, and the difference between the bit error rate and / or packet loss rate of the first information is greater than or equal to 0 and less than or equal to the third threshold, it indicates that the first channel quality determined by the terminal device meets the actual channel quality, so the adjustment information for adjusting the first channel quality can be 0. For another example, when the second transmission power is less than the first transmission power, but the network device obtains the bit error rate and / or packet loss rate of the second information, and the difference between the bit error rate and / or packet loss rate of the first information is greater than the third threshold, it indicates that the first channel quality determined by the terminal device does not meet the actual channel quality, so the adjustment information for adjusting the first channel quality will not be 0, and the first channel quality needs to be adjusted. Exemplarily, the network device may determine adjustment information for adjusting the first channel quality based on difference information between the bit error rate and / or packet loss rate of the second information, the bit error rate and / or packet loss rate of the first information, and a third threshold.

[0108] In other embodiments, the first transmission power is the same as the second transmission power. For example, when the terminal device determines that the quality of the first channel is very poor, in order to enable the network device to receive the second information, the first transmission power can be made the same as the second transmission power.

[0109] In some embodiments, the second transmit power may be determined by the terminal device according to the first channel quality. For example, when the first channel quality is poor, the second transmit power may be larger, and for another example, when the first channel quality is good, the second transmit power may be smaller. In some embodiments, the terminal device may store a correspondence between multiple channel qualities and multiple transmit powers, and the terminal device may determine the second transmit power according to the correspondence and the first channel quality; wherein the multiple channel qualities and the multiple transmit powers may have a one-to-one correspondence. In other embodiments, the second transmit power may be determined by the terminal device performing relevant calculations based on the first channel quality.

[0110] In some other embodiments, the second transmission power may be preconfigured by the terminal device. For example, the second transmission power may be a fixed value. For example, no matter which network device the terminal device needs to establish a link with, the second information may be sent to the network device at the fixed second transmission power.

[0111] In some embodiments, the method also includes: determining the location environment information of the terminal device and / or the air parameter information between the terminal device and the network device; the location environment information includes at least one of the following: the location information of the terminal device, the altitude information of the terminal device, and the geographical environment information obtained by the terminal device through a camera; the air parameter information includes at least one of the following: air attribute information, and air medium information determined based on the air attribute information; the air attribute information includes at least one of the following: temperature information, ambient brightness information, altitude information, and air environment information obtained by the terminal device through a camera.

[0115] In some embodiments, the altitude information of the terminal device may include the altitude of the terminal device. In some embodiments, the altitude information of the terminal device may be determined according to an atmospheric pressure sensor in the terminal device.

[0116] In some embodiments, the geographic environment information may include at least one of the following: mountain information, river information, plain information, etc. In some embodiments, the geographic environment information may include one or more image information captured by the terminal device through a camera, and / or one or more video information captured by the camera, and the one or more image information and / or one or more video information can reflect the geographic environment information where the terminal device is currently located.

[0118] In some embodiments, the ambient brightness information can be determined based on an ambient light sensor of the terminal device.

[0119] In some embodiments, the air environment information may include at least one of the following: cloud information, rain and snow information, haze information, sunshine information, etc. In some embodiments, the air environment information may include one or more image information captured by the terminal device through a camera, and / or one or more video information captured by the camera, and the one or more image information and / or one or more video information can reflect the air environment information currently located by the terminal device. In some embodiments, the air environment information may only include one or more image information and / or one or more video information in the target direction from the terminal device to the network device. For example, in some embodiments, the terminal device may first determine the target direction, and then display the target direction on the display screen of the terminal device, so that the user can capture one or more image information and / or one or more video information according to the displayed target direction. For another example, in some other embodiments, the user can capture image information and / or video information in various directions through the terminal device, and the terminal device selects image information and / or video information from all captured image information and / or video information according to the target direction, and uses the selected image information and / or video information as the air environment information. In some embodiments, the air environment information may include the captured original image information and / or original video information. In other embodiments, the air environment information may include compressed image information and / or video information obtained by compressing the original image information and / or original video information. In other embodiments, the air environment information may include: description information of the air environment determined by the terminal device based on one or more image information and / or one or more video information taken. Exemplarily, the description information of the air environment may include text information or drawing information.

[0120] In some embodiments, determining the first channel quality based on the location environment information and / or the air parameter information may include: at least one of: the signal strength of the response information sent by the network device received by the terminal device, the signal strength of the response information sent by the network device, the distance between the terminal device and the network device, etc., and determining the first channel quality based on the location environment information and / or the air parameter information.

[0121] In some embodiments, determining, according to the adjustment information of the first channel quality, a target transmission power of the terminal device when communicating with the network device includes:

[0122] The second transmission power is adjusted according to the adjustment information of the first channel quality to determine the target transmission power of the terminal device when communicating with the network device.

[0123] During the implementation process, since the difference between the second transmit power and the target transmit power is small, while the difference between the first transmit power and the target transmit power is large, by adjusting the second transmit power instead of the first transmit power, the power adjustment process can be shortened and the efficiency of the power adjustment can be improved.

[0124] In some embodiments, the second transmit power is adjusted according to the adjustment information of the first channel quality to obtain the target transmit power of the terminal device when communicating with the network device, which may include: when the adjustment information of the first channel quality is not 0, the second transmit power is adjusted according to the adjustment information of the first channel quality to obtain the target transmit power of the terminal device when communicating with the network device.

[0128] The location environment information and / or the air parameter information is used by the network device to determine adjustment information of the first channel quality.

[0129] In some embodiments, in order to improve the transmission reliability of the location environment information of the terminal device, the location information of the terminal device is included in the first information, and the first information is sent at the maximum transmission power of the terminal device, thereby improving the accuracy of the network device when receiving the location environment information.

[0130] In some embodiments, the importance of the air parameter information is lower than that of the location environment information, so in order for the terminal device to balance power consumption and transmission reliability, the air parameter information is included in the second information.

[0131] It should be noted that, in some other embodiments of the present application, both the location environment information and the air parameter information may be included in the first information, while the second information will no longer include the air parameter information.

[0132] For example, when the remaining power of the terminal device is less than or equal to the preset power, the terminal device determines that the first information also includes location environment information, and the second information also includes air parameter information. When the remaining power is greater than the preset power, the terminal device determines that the first information also includes location environment information and air parameter information, and the second information only includes the first channel quality.

[0150] The following takes the network device as a satellite as an example to illustrate some implementation methods in the embodiments of the present application:

[0151] Since in the related art, the time from the terminal device initiating a link request to the terminal device receiving the link budget adjustment information is very long, the present solution proposes a solution in which the terminal device actively reports the link request and the location environment information of the terminal device at one time, thereby reducing the time from the terminal device initiating a link request to the terminal device receiving the link budget adjustment information (i.e., the first channel quality adjustment information).

[0152] Fig.13 A schematic diagram of a process of communication between a terminal device and a satellite provided in an embodiment of the present application, such as Fig.13 As shown, first, the terminal device searches for the satellite through the satellite search process. For example, the terminal device searches for the satellite according to the maximum power. Then, the following steps are combined into one process for execution: the terminal device initiates a link request to the satellite, the satellite sends a response or confirmation information of the link request to the terminal device, then the terminal device sends the location information of the terminal device to the satellite, and the satellite sends the link budget adjustment information to the terminal device.

[0153] Initiate a link request, that is, the terminal device requests a link to the satellite by transmitting a signal (maximum power).

[0154] Response or confirmation of link request, that is, the satellite replies to the message after receiving the signal sent by the terminal device and prepares to establish the link process.

[0155] The terminal device replies to the position, that is, after receiving the satellite response signal, the terminal device sends the established position (mainly coordinates) to the satellite for confirmation.

[0156] To adjust the link budget, the terminal device and the satellite will adjust the strength of the received and sent signals (i.e. the power of the transmitted signal) according to the current location (altitude) and weather conditions (clouds, rain).

[0157] Fig.14 A schematic diagram of a frame structure in a communication process provided by an embodiment of the present application, such as Fig.14 As shown, the method includes: first, the terminal device sends a link request to the satellite; the terminal device receives confirmation information of the link request sent by the satellite; then, the terminal device sends location environment information to the satellite; the terminal device receives confirmation information of the location environment information sent by the satellite; then, the terminal device sends a first channel quality to the satellite, and the terminal device receives adjustment information of the first channel quality sent by the satellite.

[0158] In other embodiments, the information in the time unit corresponding to the link request and the confirmation information of the link request may be empty.

[0159] Fig.15 A schematic diagram of a frame structure in another communication process provided by an embodiment of the present application, such as Fig.15 As shown, the method includes: the terminal device sends a link request, location environment information and a first channel quality to the satellite at one time, and receives confirmation information of the link request, confirmation information of the location environment information and adjustment information of the first channel quality sent by the satellite at one time.

[0160] exist Fig.14 and Fig.15 In the present invention, the terminal device sends 5 time units of information to the satellite each time, and the satellite sends 5 time units of information to the terminal device each time.
